MACHINE FOR FACILITATING PACKING 0F MAGNETIC OBJECTS OF OBLONG SHAPE.

To all whom it may concern Be it known that I, O'r'ro ing of oblong objectsof magnetic material with the ob'ects arran ed in parallelism so as to utilize to the maximum extent all of the available space withinthe package or' spondlng parts, Figure 1 1s a vertical cross container.

Partlcularly myinvention relates to electro magnetic packing machines of the type described andshown in my Patent #1,0 80,-

I netic objects dropped into the magnetic field 435'.and Re-reissue #14290.

lVith the hitherto used machines of this kind, there are often the drawbacks that the removal of the objects from the magnetic field into which they have been previously compactly filled, is rendered very difficult or at least too inconvenient and that after transferring the objects into a container they losetheir former compactness;

These drawbacks are especially then felt wl1en,'f0r instance, nails are packed into wooden boxes which open and close on the length side or when pine or needles are packed into boxes which are too small to at once receive all the pins accumulated on the bottom of the magnetic field.

' 1 The main object of my invention is to ob viate these drawbacks;

To accomplish this object I provide'a inagneticfield which is open at its bottom and s0 arranged as to accommodate between whichthe magnetic objects can'be packed direct and simultaneously in parallelism and compactly.

Another object of my invention is to pro Vide a movable support for the container or containers, whereby the latter can'be moved into or out of the magnetic field.

A further object is to provide means for dividing the magnetic field into separate compartments to correspond with the width of the containers used and whereby the mag- GAMPER, a citizen of the Republic of Switzerland, residwheel 23.

Application filed June 1,1917. Serial No. 172.320. v

will be separated into'difi'erent tiers and be packed in parallelism in the separate containers. v 7

A still further object of my invention is to provide a packing member or plunger which on the objects falling into the magnetic field and thence into the container or containers will be moved so as to compress the objectsin the latter.

Other objects of my invention will appear from this detailed description thereof.-

In the accompanying drawings in which similar reference numerals denote correbolt having a hand wheel 7 toward and away from the pole 1, in order to reduce or enlarge this space or groove between the two poles which constitutes the magnetic field.

.The space or groove i open to the outside or, as shown, at the bottom and serves to receive the container 6 into which the mag 'netic objects are to be packed. The contamer 6 is supported on asupport 22 which is capable ofbeing moved toward and away from the magnetic field, or as shown, Verti cally in order to lift the containerinto the magnetic fieldto receive the magnetic obj ects, or to lower it when filled. In the example shown, the support isprovided with a vertically movable rack 24:, which is suitablyguide'd and with which meshes a gear 24, to be rotated by means of a hand Arranged above the 'magnetic poles isa 'movable tray 14 which may be of the same construction asthat in my previous patents.

above referred to and from which the nails or other magnetic ob ects to be packed are delivered into the magnetic fiel l plates 4 and 5 of non-magnetic material which project outwardly and laterally from the top of the poles and constitute together with guide plates of similar material av chute or hopper which extends through the magnetic field almost to the bottom edges of the poles.

Arranged centrally above the magnetic field is a plunger or packing member 19 which is movably so suspended as to be capable of being lowered into the magnetic field, and the container therein inorder to compress the magnetic objects in said container or to bring them into compact form therein. To this end the plunger 19 may be suspended by suitable means, as a cord over I a roller 19 and may be operated by means of a treadle'or the like.

The electromagnet is energized 1n 7 well known manner from an electric source 18,

I the circuit of which may be controlled througha switch 18; The switch may be operated simultaneously with the plunger 19 or separately.

' The nails or other magnetic objects to be packed in the container 6 are delivered from the tray or box 14 into the hopper 4, 5, 25 in which'they under the influence of the magnetic lines offorce created lbetween the poles willbe arranged parallel with their ends directed toward and attracted by the poles. When the space or groove between the poles after a short timehas been filled with nails the electromagnet is disenergized, in consequence of which the nails gather closer to one another and sink to the bottom of the container 6; "Simultaneously the plunger 19is lowered still more compressing the nails in the container 6. In the ex ample shown, the container assumed to be a wooden box is inserted into the space between the two poles so that the inner face of the bottom thereof is about flush with the lower edges of the poles 1 and 3; In-

this position it is held by the support 22.

When the box is filled with nails the support by the manipulation of the hand wheel 23 is lowered toipermit the removal-of the packed box and its replacement by an empty one, which is then raised into, the magnetic field; .7

In this manner it is possible to pack the objects directly into the'boxes without the necessity of I subsequent repacking, which might cause disarrangement of'the objects.

If the box has been only partly filled the same can be lowered until the upper layer of the nails is even with the bottom edges 'of'the poles. Then a fresh supply of nails is dropped into the field which are packed a *in the container in the same manner as before. I 7 v Thelparts ofthe poles land 3 between which the box is to be mounted are cut away as at 1', 3', to a depth substantially equal to boxes or containers used. 1

vent the nails from jumping out of the'box when the electromagnetis suddenly restarted and before the boxis entirely removed from within the field.

If it"is desired to pack nails or smaller objectssuch 'as needles in several boxes simultaneously, the magnetic field may be arranged in several tiers-or compartments, each one to receive a separate container.

Such form of construction 1s illustrated in Figs. '3 and 1. Here a member 26 of non magnetic material is inserted into the space formed between the magnetic poles which is provided with a number of partition plates 26, to extend at airight angle to the surfaces of the poles and spaced apart dis tances about equal to the lengths of the containers 6- In the example shown, double plates 26 are used for'each'ti'er, with a space 26 between two adjoining plates which is about equal to the thickness of two walls of adjoining containers The member 26 is made of such a height as to extend throughout the entire heightofthe magnetic field to about the lower edges thereof, so that they will project into the containers 6. The member 26 may be removab'ly mounted between the magnetic poles to be exchangeable according to the sizesof the Like in the first modification therelisi' a plunger or packing'member 27 suitably'su'spended from aroller 27 or the like 'above Y the magnetic field, and which in the present case is composed of a number of members similar to the member 19, each one adapted on lowering the member 27 to enter a compartment or tier and a'box 6 to the objects therein. 1 v

The operation of this modified construccompress tion is similar to that of the first construction. The containers, which are assumedin the present example to-be paper boxes to re 'ceiye needles, pins or other small magnetic ob ects are supported on the vertically movable support 22. The needles or the like are deliveredfrom the tray or box 14 into the different compartments or tiers formed by "the member 26. In these compartments the objects become arranged in parallelism and on disenergizing the electromagnet sink 111130 the containers in which they are compressed by the multiple plunger 27 It is obvious that my invention may be carried out in machines of different forms, without departing from the principle of my invention, and for this reason I do not wish to restrict myself to the specific construction and detalls shown and described,but, wish V netized poles forming a magnetic field, nonmagnetic partitions lnsaid field sub-divid-v the two modifications to be considered ithin the scope of the appended claims, as ex- "2131113168 of the embodiment of my invention.
